Desclafani is coming off an excellent start Tuesday against the Padres. He pitched 6 M innings of one-run ball, allowing just three hits and one walk while whiffing three. He’s given up three or fewer runs in each of his last six starts. The righty has dominated Colorado this season, going 3-0 with a 1.85 ERA and 1.068 WHIP over four starts. In seven career appearances vs. Colorado, he’s 4-1 with a 2.83 ERA.
